I would like to make this series merge in 2.0 before hard freeze because it
would allow a production usage of quorum so it would let me move on the rest of
the block filter infrastructure.(throttling as filter, filter insertion and
removal etc..)
in v2:
Fix typos and spelling mistakes [Eric]
Fix alignement [Eric]
Remove comments about Fam's new API [Eric]
Add a new test to check that the to-replace-node-name is locked as in use
during mirroring [Benoît]
This patch allow to build a mirror of a block device and replace an arbitrary
named node of the graph with the mirror.
The obvious first usage is Quorum: with this patch one quand drive-mirror the
block device say quorum0 and then bdrv_swap the result in place of a broken
quorum file (dead filer for example).
The second patch implement drive-mirror tests for this mode.
Benoît Canet (2):
block: Add node-name and to-replace-node-name arguments to
drive-mirror.
qemu-iotests: Add TestRepairQuorum to 041 to test drive-mirror
node-name mode.
